Which of the following is a disadvantage to using equations?
The graph of an equation is a visual representation of the values that satisfy the equation.
To determine if a relationship is linear from a table, check if the differences in the y-values (output) corresponding to equal differences in the x-values (input) are constant. For a graph, a linear relationship will appear as a straight line. In an equation, if the equation can be expressed in the form (y = mx + b), where (m) and (b) are constants, it indicates a linear relationship.
You could put the equation in slope-intercept form or in parent linear function or even make a table of values.
Just like any other equation, you can set up a table of x values, and calculate the corresponding y values. Then plot the points on the graph. In this case, it helps to have some familiarity with quadratic equations (you can find a discussion in algebra books), and recognize (from the form of the equation) whether your quadratic equation represents a parabola, a circle, an ellipse, or a hyperbola.
I would set up a table of values and calculate several of the values of the variables (I would try to calculate the "interesting" values setting one to zero and calculating the other(s), guessing at a maximum or minimum value etc. Then I would plot the values on graph paper.

Depends what the graph is.

A table you make to find the coordinates to graph.
There are three ways: a table, a graph, and an equation.
Any explanation will depend on whether or not the table of values and the graph are related to one another. Nothing in the question indicates that they are.

The equation which remains true for each set of variables in the table.
